LASTING MACHINE HAVING SPINDLE BRAKE Original Filed Oct. 12, 1961 16Sheets-Sheet 16 United States Patent 3,241,164 LASTING MACHINE HAVINGSPINDLE BRAKE Jacob S. Karnborian, 133 Forest Ave., West Newton, Mass.Continuation of application Ser. No. 144,696, Oct. 12, 1961. Thisapplication Mar. 15, 1963, Ser. No. 266,150 14 Claims. (Cl. 12-401) Thisapplication is a continuation of pending application Serial No. 144,696filed October 12, 1961, and now abandoned.

This invention relates to a lasting machine such as that disclosed incopending application Serial No. 107,156 filed May 2, 1961, now PatentNo. 3,189,924.

The copending application discloses a machine for assembling a shoeupper on a last and wiping the heel portion of the upper upon an insolelocated on the last bottom that includes a spindle pivotally mounted,for movement toward and away from a heel seat lasting unit, on thepiston rod of an air actuated motor. A last supporting means is mountedat the top of the spindle. A swivel block is pivotally mounted on thespindle below the last supporting means for swinging movement about theaxis of the spindle, and an upper tensioning unit is mounted on theblock. The upper tensioning unit comprises a toe rest roller, a pair oftoe pincers and two pairs of side pincers. The heel seat lasting unit,which is movable from an out-of-the-way position to a working position,comprises heel clamping means and wiping means movable in apredetermined plane. A hold-down unit is also provided that includes ahold-down foot normally positioned slightly below the bottom of thewiping means.

In operating the machine, a last having an upper mounted thereon and aninsole located on its bottom is placed bottom-up on the last supportingmeans so that the toe of the last and upper is supported or held by thetoe rest roller and the toe and forepart portions of the upper arerespectively gripped and held by the toe and side pincers. The pincersare then moved forwardly in unison to stretch the upper about the last,the spindle is then swung about the piston rod to a position adjacentthe heel seat lasting unit, the piston rod is elevated to force theinsole against the hold-down foot and clamp the shoe and last betweenthe hold-down foot and the last supporting means, the pincers are raisedin unison to stretch the upper tightly on the last, the heel seatlasting unit is moved from its out-of-the-way position to its workingposition, the clamping means are actuated to clamp the upper against thelast, the wipers are moved forwardly to wipe the margin of the upperupon the insole, and the hold-down foot is raised during the forwardmovement of the wipers to apply bedding pressure by the application offorce by the motor directly against the bottom of the wiping means.

It is desirable that, when the heel clamping means engages the last, theheel of the last be symmetrically disposed with respect to the centerline of the Wiping means and clamping means. The line of symmetry of theheel of the last varies dependent on the size and style of the last andon whether a left or right foot last is used. The instant inventionprovides an arrangement for locking the swivel block to the spindle insuch a position that, for the particular last used, the heel of the lastis in proper alignment with the center line of the wiping and heelclamping means. This arrangement comprises a brake movable radially in ahole in the swivel block toward and away from the spindle and an airactuated motor mounted on the swivel block having a piston rod inalignment with the brake. A manually actuated valve is provided whichnormally supplies air under pressure to the motor to cause its pistonrod to push the brake against the spindle and thus lock the swivel blockto the spindle. The valve may be actuated to cut off the air to themotor, at which time the swivel block is swung to a selected 3,241,164Patented Mar. 22, 1966 position about the spindle and relocked to thespindle upon release of the valve.

The machine comprises a frame 10 having an inclined plate 12 (FIG. 1).An air actuated motor 14 mounted on the plate 12' has a piston rod 16extending upwardly therefrom that is vertically guided in a guidebearing 18 secured to the frame. A post 20 is pivotally secured to thepiston rod 16 by a pivot 22. A rod 24 is received in a socket in theupper end of the post 20. A collar 26 (FIG. 3) is slidably mounted onthe rod 24. A rotatable shaft 28 is threaded into the collar 26, wherebyrotation of the shaft adjusts the position of the collar on the rod. Asleeve 30 is slidably mounted on the rod 24 and rests on the collar 26.A swivel block 32 (FIGS. 4 and 5) is pivotally mounted on the sleeve forswinging movement about the axis of the sleeve with the bottom of theblock 32 resting on the collar 26, and a snap ring 34 in the sleeve 30engaging the top of the block 32. A last pin holder 36 is mounted at.the upper end of the rod 24. A last supporting 'plate 38 having aconvex lower surface is received in a concave groove at the top of thelast pin holder 36, and a last pin 40 is secured to the last pin holderand projects upwardly therefrom through a hole in the last supportingplate 38. Members 20, 24, 26 and 30 form the aforementioned spindle andmembers 38 and 40 form the aflorementioned last supporting means.

An air actuated motor 42 (FIGS. 4 and 5) is secured by bolts 44 to therear of the swivel block 32. A slide 46 is slidably mounted in a hole 48in the block 32, with the slide in alignment with the piston rod 50 ofthe motor 42. A brake pad 52 made of resilient, flexible material issecured to the front of the slide 46, the pad having a concave facecorresponding in shape to the outer periphery of the rod 24. The slideand brake pad comprise the aforementioned brake. A cut-out 54 isprovided in the sleeve 30 to accommodate the brake pad 52. A pin '56mounted in the block 32 is received in a peripheral groove 58 in theslide 46 to prevent rotation of the brake about its axis.

The swivel block has a groove 60 on each side thereof, and parallel bars62 are rigidly mounted in each groove 60 to extend forwardly of theblock 32. An air operated motor 64 is pivotally connected to each bar 62to extend forwardly of the block 32. The piston rods 66 of the motors 64are rigidly connected to a head 68 forming part of an upper tensioningunit 70 that is slidably mounted on the bars 62.

Referring to FIGS. 6 and 7, the unit 70 includes a toe rest roller 72mounted on a toe post 74, the toe post and the toe rest roller beingconnected to a wheel 76 whereby rotation of the wheel imparts aheightwise adjustment of the toe post and toe rest roller. An airoperated motor 78 mounted on the unit 70 has a piston rod 80 that isconnected to a T-bar 82 that is slidably mounted for upand-down movementin the unit 70. At the top of the upright limb 84 of the T-bar, there ismounted a front pincers bracket 86. The bracket 86 has a pair of uprightslots 88 which receive studs 90 that are threaded into the T-bar 82 tothereby adjustably mount the bracket 86 on the T-bar. A pincers 92 ismounted on the bracket 86. The pincers 92 comprises a stationary pincersjaw 94 n'igidly connected to the bracket 86 and a movable pincers jaw 96swingably mounted on the bracket 86. An air operated motor 98, mountedon the bracket 86, has a piston rod 100 engageable with the pincers jaw96, the latter member being normally urged to open position by a spring102. A side pincers bracket 104 is slidably mounted on each prone leg106 of the T-bar 82. A shaft 108 having right and left hand threads atits opposite ends is screwed into bosses 110 that are secured to theside pincers bracket 104. Each bracket 104 supports a side pincers 112.Each side pincers 112 comprises a fixed jaw 114 rigidly connected to abracket 104 and a movable jaw 116 pivotally mounted on a bracket 104 bya pivot 118 and pivotally connected to the piston rod 120 of an airoperated motor 122 that is secured to an extension 124 on each bracket104. The position of the brackets 104 and the pincers 112 carriedthereby may be adjusted by rotating the shaft 108.

The post 20 is pivotally connected to the legs 126 of a forked pitman128 that straddles the post (see FIGS. 8 and 9). The pitman 128 ispivotally and eccentrically connected to a crank 1130. The crank 130 isconnected to a shaft 132 which in turn is pivotally mounted in the frame10. The shaft .132 has a gear 134 secured thereto that is in mesh with arack 136 mounted on a D-shaped rack support 138, the rack being slidablyguided in gibs 4- 140 located in the frame 10. An air operated motor142, mounted in the frame 10, has a piston rod .144 connected to therack support 138 to effect vertical movement of the rack 136 and henceswinging movement of the post 20 about the pivot 22. A shock absorber146 is interposed between the frame 10 and the rack 136 to eliminatechattering and ensure a smooth operation when the rack is caused to moveupwardly or downwardly in the frame.

A heel seat lasting uni-t 148 is mounted in the frame 10 rearwardly ofthe upper tensioning unit 70. Referring to FIGS. 10 through 17, the unit148 comprises a main slide plate 150 slidably mounted for forward andrearward movement on gibs 152 in the frame 10 (see FIG. 12). A block 154is secured to the plate 150 and is slidable in a slot 156 formed in atable 158, which table forms a part of the frame 10. A floating actuator160 is secured to the block 154. The actuator 160 comprises a bar 162depending from and rigid with the block 154. An air operated motor 164is pivoted to the bar 162 and has a piston rod 166 extending upwardlytherefrom. A pair of toggle links 168 and 170 are pivoted at theiradjourning ends to the piston rod 166 and are respectively connected attheir opposite ends to the bar 162 and to a nut 172. A screw 174 isrotatably mounted in hangers 176 and 178 depending from the table 158,extends through a clearance opening 180 in the bar 162 and is threadedinto the nut 172. The screw 174 is connected through a gear train 182and a shaft 184 to a wheel 186. Thus, rotation of the wheel 186 causesthe nut 172 to move axially of the screw 174 and causes the floatingactuator 160, the block 154, the main slide plate 150 and the memberscarried thereby to move forwardly or rearwardly in the frame. Actuationof the motor 164 to open or close the toggle linkage formed by themembers 166, 168 and 170 will also cause the main slide plate 150 andthe members carried thereby to move forwardly or rearwardly in theframe.

A pair of air actuated motors 188 are mounted on the plate 150 (FIGS. 14and 15). Each motor 188 has a piston rod 190 that is pivotally connectedto a lever 192 by a pivot 194. The levers 192 have legs 196 extendingtoward each other from the pivots 194 and legs 198 extending forwardlyand divergently from the pivots 194. The legs 196 are pivotallyconnected by pivots 200 to a slide 202. A pair of tension springs 204and 206 are connected at their opposite ends to arms 208 that are fixedto the legs 196. The springs force the levers 192 about the pivots 194to the position shown in FIGURE 14 where the contiguous faces of thelegs 196 abut each other. The slide 202 is slidably mounted in gibs 210mounted on the plate 150. The lever legs 198 have studs 212 adjustablymounted in their extremities, and the studs 212 are affixed to the endsof a U-shaped heel clamping pad 214 made of a flexible material such asleather. A pair of sprocket chains 216 are wrapped around the outerperiphery of the pad 214. Each chain 216 is anchored at one end to astud 212 and is secured at its other end to a projection 218 extendingforwardly of the slide 202. A pair of spring return air actuated motors220 are mounted in each of the lever legs 198 (FIGS. 14 and 16). Themotors 220 have pistons 222 extending toward the pad 214 below thechains 216. A pressor member 224 is aflixed to each piston 222.

A bridge 226 is anchored at its end to the sides of the main slide plate150 and extends thereover. An air operated motor 228 is secured to a rib230 at the rear of the main slide plate 150. The piston rod 232 of themotor 228 has a rack 234 thereon that is in mesh with a gear 236rotatably mounted beneath the bridge 226 on a pin 238 fixed in thebridge. A wiper supporting slide plate 240 is slidably mounted on gibs242 in the frame (FIG. 12). The plate 240 has a slot 244 extendingtransversely to the rack 234 which receives an eccentrically mountedcrank pin 246 depending from the gear 236. The piston 232 has anenlargement 248 to which are pivoted the ends of links 250. The oppositeends of'the links 250 are pivoted to wiper cams 252, and a Wiper 254 ismounted in each wiper cam. The wiper cams 252 have curved cam slots 256with a center of curvature at the point where the wipers diverge fromeach other, indicated by the numeral 258 in FIG. 17. The wiper cams 256rest on the plate 240, and the plate 240 has rollers 260 extendingupwardly therefrom into the cam slots 256.

A hold-down unit 262 is mounted on a frame cover 264 located above theplates 150 and 240 and the wiper cams 252. The unit 262 comprises alever 266 pivoted to a clevis 268 on the cover 264 by a pivot 270 (seeFIGS. 13 and 18). A link 272 is pivoted to the cover 264 below the pivot270, and both the lever 266 and the link 272 are pivotally connected toa hold-down foot 274. The lever 266, link 272 and foot 274 thus form aparallel linkage mechanism whereby counterclockwise movement of thelever (FIG. 18) imparts a substantially rectilinear downward movement tothe foot 274 and clockwise movement of the lever 266 imparts asubstantially rectilinear upward movement to the foot 274. A pin 276 isrotatably mounted in the cover 264 rearwardly of the pivot 270, and aroller 278 is afiixed to the pin 276. A roller 280 is rotatably mountedin a clevis 282 that is slidably mounted for up and down movement at therear end of the lever 266 opposite the roller 276. A screw 284 bearsagainst the upper surface of the clevis 282 to limit the upward movementof the clevis 282 in the lever 266. An air operated spring return motor286 is secured to the cover 264. The piston rod 288 of the motor 286 hasa cam 290 secured thereto that is interposed between the rollers 278 and280. A tension spring 292 extending from the pin 276 to a pin 294 fixedto the lever 266 urges the roller 280 against the cam 290. The cam 290has a high portion 296 that is normally interposed between the rollers278, 280. The actuation of the motor 286 to bring a low portion 298 ofthe cam between the rollers will cause the spring 292 to move the roller280 downwardly against the cam portion 298, swing the lever 266, andthereby raise the hold-down foot 274, for a purpose that is explainedbelow.

Although the apparatus of the instant invention has general utility inassembling an upper on a last and heel seat lasting the upper onto theinsole, it has particular utility in carrying out the method disclosedin pending application Serial No. 80,919 filed January 5, 1961, nowPatent No. 3,144,670. In the referred to method, a flaccid countercoated on both of its surfaces with adhesive is inserted in a pocketformed between an upper and a liner at the heel of the upper, the upperis draped about a last, tensioning forces are applied at the toe end ofthe upper to wrap the upper about the heel end of the last and initiatethe molding of the counter to the shape of the last, the last is movedto a heel seat lasting position and forced upwardly'against a hold-down,upward tensioning forces are applied at the toe end of the upper toassemble the upper on the last, a clamping force is applied at the heelof the last to maintain the upper stationary on the last and to completethe molding of the counter to the shape of the last, and the margins ofthe upper and counter are wiped down onto an insole located on thebottom of the last to thereby unite the lasted margin of the upper tothe insole by adhesively bonding the counter to the upper and insole.

wardly (FIGS. 5 and 26), cause the brake pad 52 to bear against the rod24, and thus lock the swivel block 32 and the upper tensioning unit 70carried thereby to the rod 24. An actuation of the valve 302 by pushingthe valve stem 306 serves to cut off the motor 42 from the source ofpressurized air and thus unlock the swivel block with the center line ofthe last.

6 32 from the rod24. The swivel block 32 may now be rotated about theaxis of the rod 24 to a desired position, after which the valve stem 306is released to lock the swivel block to the rod in the desired position.

In setting up the machine for a particular size and shape of last, theadjustments described in the aforementioned Patent No. 3,189,924 areperformed. A last 308 is provided having an insole 310 mounted on itsbottom and an upper 312 draped thereon. A liner 314 is secured to theheel of the upper to engage the heel of the last, and a counter 316 islocated in the pocket formed between the upper and the liner. The lastis placed bottom-up on the last supporting plate 38 with the pin 40entering the conventional last pin hole in the last. The toe portion ofthe upper and last is supported on the toe rest roller 72.

In lasting a shoe, it is desirable that the heel be symmetricallydisposed with respect to the center line of the wipers 254 and theclamping pad 214. Due to the curvature of the last, this line ofsymmetry does not coincide As seen in FIG. 25A, with a right foot last,the center line of the bars 62 and the upper tensioning unit '70 carriedthereby is offset clockwise from the center line of the wipers 254 andclamping pad 214 in order for the line of symmetry of the heel tocoincide with the center line of the wipers and the clamping pad. By wayof contrast, as seen in FIG. 25B, with a left foot last, the center lineof the bars 62 and the upper tensioning unit 70 carried thereby isoffset counterclockwise from the center line of the wipers and clampingpad in order for the line of symmetry of the heel to coincide with thecenter line of the wipers and the clamping pad.

After placing the last-mounted shoe in. the machine, the valve 302 isactuated to release the brake pad 52, after which the swivel blockisswung and the valve 302 released to reapply the brake pad so that, forthe particular shape and size of last utilized, the center line of thelast heel is in the desired position relative to the center line of thewipers and clamping pad. The toe end of the upper is now insertedbetween the jaws of the toe pincers 92 and the forepart portions of theupper are in serted between the jaws of the side pincers 112. At thistime the upper end of the liner 314 is substantially level with theinsole 310 and the upper margins of the counter 316 and upper 312 at theheel end of the last extend above the insole 310 as indicated in FIGS.20A and 20B.

A pedal 318 (FIG. 1) is now depressed to operate the several airactuated motors by the control system disclosed in the above referred toPatent No. 3,189,924. The motors 98 and 122 are actuated to cause thefront pincers 92 and the side pincers 112 to grip the margin of theupper as indicated in FIGS. 20A and 20B. This is followed by anactuation of the motors 64 to cause the upper tensioning mechanismincluding the pincers 92 and 112 to move forwardly on the bars 62 tothereby horizontally stretch the upper in the direction of the toe ofthe last and cause a firm wrapping of the upper about the heel of thelast and a tension force on the counter to start to mold it to the shapeof the last.

The motor 142 is now actuated to lower the piston rod 144 and the racksupport 138 to thereby swing the post 20 about the pivot 22 to aposition where the shoe is adjacent to but not in engagement with theheel seat lasting unit 148 and the hold-down unit 262. In this positionthe post 20 is in an alignment with the hold-down foot 274 but theinsole 310 is below the bottom of the holddown foot. In addition, inthis position, the shoe upper and last are not in engagement with theheel clamping pad 214.

The motor 14 is now actuated to raise the post 20 and thus raise thelast and shoe until the insole 310 bears against the hold-down foot 274.The hold-down foot at this time is'in its normal down position and is solocated that its bottom is below the bottoms of the wipers 254 an amountsubstantially equal to the thickness of the upper margin and thecounter. In this position the shoe and last are clamped between thehold-down foot 274 and the last supporting plate 38, as indicated inFIG. 21, with the upwardly facing surface of the insole slightly belowthe top surface of the clamping pad 214 and the bottom surfaces of thewipers 254.

The motor 78 is now actuated to raise the T-bar 82 thereby raising thepincers 92 and 112 to apply an upward tension to the margin of the upper312 at its toe and forepart portions to thereby stretch the uppertightly on the last and assemble it in proper position for thesubsequent heel seat lasting operation. Since the last and shoe areclamped at this time between the foot 274 and the plate 38, upwardmovement of the pincers does not shift the last.

The motor 164 on the floating actuator 160 is now actuated to raise thepiston rod 166 and straighten the toggle links 168 and 170. Thestraightening of the toggle links moves the block 154 and the heel seatlasting unit 148 carried thereby from its normal out-of-the-way positionto a position adjacent the shoe and last.

The motors 188 are now actuated to cause the piston rods 190 to move thelevers 192 and the clamping pad 214 carried thereby toward the heel ofthe last with the slide 202 sliding in the gibs 210. During thismovement the spring 204 and 206 maintain the lever legs 196 in abuttingrelation and the lever legs 198 in open position until the bight 328 ofthe pad 214 engages the shoe as indicated in dotted lines in FIG. 22. Atthis time the bight of the pad and the slide can no longer moveforwardly so that continued forward movement of the piston rods 190causes the levers 192 to swing toward each other about the pivots 194 tocause the legs 322 of the pad to move toward each other and engage theshoe upper as indicated in solid lines in FIG. 22. This arrangementprovides for an initial contact of the pad 214 at the heel end of theshoe and then a progressive engagement of the pad along the sides of theshoe extending forwardly of the heel to ensure a smoothening out of anywrinkles there may be in the upper and a smooth, firm clamping of theupper against the last.

The motors 220 are now actuated to force the presser members 224 againstthe pad 214 and thereby press the pad against the shoe and last. As seenin FIG. 23, the presser members engage the pad 214 toward the bottomopposite the portion of the last that curves inwardly to form a lastportion having a relatively narrow width. The presser members 224 ensurethat all of the pad 214 bears against the last 308 to thereby hold theupper firmly in place during the subsequent lasting operation and tocomplete the molding of the counter 316 to the shape of the last.

The motor 228 is now actuated to advance the piston rod 232, the rack234 and the piston rod enlargement 248 to cause the wipers 254 to bemoved from the dotted line position of FIG. 24B to the solid lineposition and wipe or fold the margin of the upper 312 and counter 316down against the insole 310. The wiping pressure completes the moldingof the counter and causes the counter, through the adhesive on itssurfaces, to bond the wiped-in-margin of the upper to the insole. Theforward movement of the piston rod 232, through the links 250, causesthe wipers 254 to move toward each other about the point 258. Theforward movement of the piston rod 232, through the rack 234, the gear236, the slot 244 and the pin 246 also causes the plate 240 to moveforwardly thereby providing a forward movement of the wipers as well asan inward movement about the point 258. Since the slot 244 extendsnormal to the path of movement of the piston rod 232, the movement ofthe slot from the rightward position of FIG. 17 to the leftward positionindicated in phantom causes the plate 248 initially to move forwardlyalmost as fast as the piston rod 260 and then to gradually slow down,until,

towards the end of the stroke of the piston rod, the plate hassubstantially no forward motion. The result of this is that initiallythe wipers move forward with substantially no inward movement about thepoint 258, and at the end of the wiper stroke the wipers move towardeach other about the point 258 with very little forward movement. Thisproduces a wiping action where the force created by the wipers in movingacross the insole 318 at any given point is substantially radial to thecurvature of the last at that point.

During the forward stroke of the piston rod 232, the motor 286 isactuated to move the cam 290 forwardly to present the low cam portion298 between the rollers 278, 280 and thus cause the raising of thehold-down foot 274 as indicated in FIG. 24A. The motor now appliesupward pressure by the last directly against the wipers to provide anoverwiping and bedding pressure between the wipers and the wiped-inmargin of the upper during the latter part of the wiper stroke and alsoafter the termination of the wiper stroke.

This concludes the lasting operation. The pedal 318 is now released bythe operator which substantially simultaneously causes the actuation ofthe motors 98 and 122 to open the pincers 92 and 112 to release the toeand forepart portions of the upper margin, the actuation of the motor 78to lower the T-bar 82 and the pincers 92 and 112 carried thereby totheir initial position on the upper tensioning unit 70, the actuation ofthe motors 188 to open the clamping pad 214, the actuation of the motor164 to return the heel seat lasting unit 148 to its originalout-of-the-way position, and the actuation of the motors 64 to returnthe upper tensioning unit 70 to its original position on the bars 62.This is followed by the concurrent actuation of the motor 14 to lowerthe post 20 and thereby lower the shoe and last, the actuation of themotor 228 to retract the wipers 254, and the actuation of the motors 220to return the pressure members 224 to their original positions. Duringthe retraction of the wipers 254, the motor 286 is actuated to retractthe piston rod 288, return the high cam portion 296 between the rollers278 and 280 and thereby lower the hold-down foot 274 to its originalposition. The motor 142 is now actuated to raise the rack support 138and thereby swing the post 20 away from the heel seat lasting unit 148back to its original position.

It should be understood that the present disclosure is for the purposeof illustration only and that this invention includes all modificationsand equivalents that come within the scope of the appended claims. Termsin the claims such as top, below and forwardly are intended to describethe relative positions and paths of movement of the parts and should beconstrued accordingly.
